A formidable coalition of 44 state attorneys general has formally challenged the Commodity Futures Trading Commission’s (CFTC) proposed regulatory framework for prediction market platforms, asserting that the federal agency lacks the statutory authority to oversee sports-related event contracts. The strong rebuke, delivered in a letter to the CFTC on Monday, coincided with the close of the public comment period for the agency’s initial draft rule, which primarily targets the burgeoning sports offerings on these platforms. This confrontation intensifies an already heated jurisdictional battle between federal and state regulators over the rapidly expanding prediction market industry.
The Heart of the Dispute: Federal Overreach vs. State Sovereignty
The letter, spearheaded by Ohio Attorney General Andy Wilson, argues unequivocally that "The Proposed Rule goes beyond the CFTC’s statutory powers, is in tension with the Constitution, and would otherwise be arbitrary and capricious in its current form." The attorneys general demand that the CFTC withdraw its current proposal and instead craft a new rule that explicitly clarifies that "sports bets and gambling cannot be traded on [designated contract markets], but are instead subject to state law." This stance underscores a fundamental disagreement over whether sports-related event contracts constitute legitimate financial derivatives, falling under the CFTC’s purview, or are essentially a form of sports betting, traditionally regulated at the state level.
Notably, five states—Florida, Georgia, New Hampshire, Missouri, and Texas—did not sign the letter, suggesting a degree of internal division or differing legal interpretations among state authorities regarding this complex issue. Their absence from the coalition’s unified front could be indicative of varying state-level approaches to gambling regulation, or perhaps a more cautious stance on challenging federal agencies directly.
A Market in Flux: The Rise of Prediction Platforms and the Regulatory Lag
The current jurisdictional tussle is a direct consequence of the explosive growth experienced by prediction market exchanges over the past year. These platforms, which allow users to wager on the outcomes of future events—ranging from political elections and economic indicators to, most controversially, sports results—have seen their volumes surge. The 2026 FIFA World Cup, in particular, served as a catalyst, driving platform volumes to unprecedented heights. Industry analysts estimate that global prediction market volumes related to the World Cup alone exceeded $5 billion, with a significant portion originating from U.S. users, highlighting the immense commercial interest and consumer engagement. This rapid expansion has created a regulatory vacuum, prompting both federal and state authorities to assert their control.
The CFTC, and the prediction market platforms themselves, contend that all event contracts are "swaps"—a type of derivative financial instrument that falls squarely within the commission’s regulatory mandate under the Commodity Exchange Act (CEA). They argue that these contracts, by allowing participants to hedge against or speculate on future outcomes, function as legitimate financial tools, distinct from traditional gambling. The CFTC’s long-standing mission is to foster open, competitive, and financially sound markets, and from its perspective, regulating these contracts is a natural extension of its authority over derivatives.
However, state attorneys general and various state gaming commissions firmly believe that the sports-related contracts offered on these platforms bear an undeniable resemblance to traditional sports betting. They point to the mechanics of these contracts, where participants risk capital on the outcome of a sporting event, with payouts contingent on correct predictions. States have historically held primary jurisdiction over gambling activities within their borders, a prerogative that was significantly bolstered by the 2018 Supreme Court decision in Murphy v. NCAA, which effectively overturned the federal Professional and Amateur Sports Protection Act (PASPA) and paved the way for states to legalize sports betting. This ruling created a patchwork of state-specific regulations for sports wagering, and states are keen to maintain their authority in this lucrative and socially sensitive area.
The CFTC’s Proposed Rule: A Deep Dive into "Gaming"
In June, the CFTC unveiled the first draft of its proposed rule on regulating prediction markets. The draft focused heavily on the contentious sports-related event contracts, outlining criteria for which types might be prohibited. A crucial element of this proposal was the commission’s attempt to define "gaming." The CFTC’s definition characterized "gaming" as an activity done for recreation or entertainment, governed by specific rules, and based on measurable outcomes determined by skilled activity during the event itself.
This definition, however, drew immediate criticism from various stakeholders, including established financial institutions. CME Group, a major derivatives marketplace, strongly disagreed with the CFTC’s interpretation. Jonathan Marcus, CME general counsel, articulated this concern in a letter to the CFTC, stating, "By defining ‘gaming’ as the sport itself rather than the financial wagering on the sport, the CFTC’s definition suggests the [Commodity Exchange Act] is preempting state sports regulations, which is a striking overreach." CME Group’s concern highlights the potential for the CFTC’s broad definition to inadvertently encroach upon areas traditionally regulated by states, particularly those pertaining to the conduct of sports and associated activities. This stance is particularly noteworthy given CME Group’s own involvement in the prediction market space, acting as the CFTC-regulated exchange for FanDuel’s sports prediction markets through their "FanDuel Predicts" partnership launched in December 2025. This dual role underscores the complex and often contradictory positions entities find themselves in as the regulatory landscape evolves.
Conversely, newer prediction market platforms, such as Rothera, which launched in June, have argued in favor of the CFTC’s proposed "gaming" definition precisely because it focuses on the activity itself rather than the act of wagering. Rothera CEO Thomas Chippas contended in his letter to the commission that "A definition keyed to wagering, or to ‘risking something of value’ would, as the Commission recognizes, sweep in every event contract." Chippas further added, "Rothera agrees that a definition keyed to ‘wagering’ should be rejected." This perspective aligns with platforms that seek to differentiate their offerings from traditional gambling, emphasizing their nature as financial instruments tied to event outcomes.
The Legal Battleground: Federal Preemption and Ongoing Litigation
The CFTC has consistently invoked the principle of federal preemption in its court proceedings across the U.S., asserting its exclusive jurisdiction to regulate prediction markets. Federal preemption is a legal doctrine under the Supremacy Clause of the U.S. Constitution, which holds that certain federal laws take precedence over conflicting state laws. The commission is currently engaged in litigation with nine states, defending its belief that its authority over "swaps" extends to all event contracts offered on these platforms, regardless of their underlying subject matter. These lawsuits are complex, often involving intricate interpretations of financial law, gambling statutes, and constitutional principles.
The legal arguments hinge on whether event contracts, particularly those related to sports, meet the legal definition of a "swap" under the CEA. If they are deemed swaps, then federal law, specifically the CEA, would likely preempt state laws attempting to regulate them as gambling. However, if courts find that these contracts are primarily gambling, then states would retain their traditional authority. The stakes are incredibly high, not just for the platforms and regulators, but also for consumers, who could face a confusing and inconsistent regulatory environment depending on the outcome of these disputes.
A Patchwork of Decisions: Diverging Judicial Outcomes
The ongoing legal battles are already yielding diverging results, reflecting the novelty and complexity of the issues at hand. In late June, a Michigan judge issued a ruling that blocked the prediction market platform Kalshi from offering sports bets to residents of the state. This decision sided with the state’s interpretation that such contracts constituted illegal gambling under Michigan law, signaling a victory for state-level regulation.
However, just weeks later, a federal judge in Minnesota issued a contrasting decision. On Monday, the judge temporarily blocked a statewide ban on prediction markets from taking effect, granting a preliminary injunction to a platform challenging the state’s prohibition. This ruling, even if temporary, represents a setback for state efforts to outright ban or exclusively regulate prediction markets, reinforcing the CFTC’s argument for federal oversight. These disparate outcomes underscore the likelihood that this issue will eventually require resolution at the highest judicial level.
Broader Implications and the Road Ahead
Observers of prediction markets widely agree that the Supreme Court will likely have the final say in determining who ultimately gets to regulate sports-related event contracts. The legal questions involve fundamental aspects of federalism, the interpretation of financial statutes, and the evolving definition of what constitutes "gambling" in the digital age. A Supreme Court ruling would provide much-needed clarity, establishing a precedent that would impact not only prediction markets but potentially other innovative financial products that blur the lines between traditional finance and wagering.
The outcome of this regulatory struggle carries significant implications for various stakeholders. For prediction market platforms, a favorable ruling for the CFTC could provide a clearer, more unified regulatory pathway, potentially fostering innovation and growth across state lines. However, it could also mean stricter oversight and compliance burdens typically associated with federal financial regulation. Conversely, if states prevail, platforms might face a fragmented regulatory landscape, requiring compliance with 50 different sets of rules, which could hinder scalability and increase operational costs.
For consumers, the implications are equally profound. A federal framework could offer consistent protections and standards, while a state-led approach might lead to varying levels of consumer safeguards and access depending on their location. Furthermore, the economic impact is substantial. States view sports betting as a significant source of tax revenue, and if prediction markets are deemed gambling under state law, they would seek to tax them accordingly. If they fall under federal financial regulation, states would lose out on this potential revenue.
The debate also touches upon the very nature of financial innovation and regulatory adaptation. As technology continues to create new ways for individuals to interact with markets and speculate on future events, regulators face the arduous task of fitting these novel instruments into existing legal frameworks, which were often designed for a different era. The conflict between the CFTC and state attorneys general over sports prediction markets is a microcosm of this broader challenge, highlighting the tension between promoting innovation and ensuring consumer protection, market integrity, and traditional jurisdictional boundaries. Until the Supreme Court or a comprehensive legislative solution emerges, the future of sports prediction markets in the U.S. remains shrouded in legal and regulatory uncertainty, a testament to the dynamic interplay between technology, commerce, and governance.
